Arnaldo Carvalho de Melo c9d77f0a0c tools headers: Update the syscall tables and unistd.h, to support the new 'rseq_slice_yield' syscall ... Picking up the changes from these csets: 2153b2e891 ("sparc: Add architecture support for clone3") 99d2592023 ("rseq: Implement sys_rseq_slice_yield()") 4ac286c4a8 ("s390/syscalls: Switch to generic system call table generation") This makes 'perf trace' support it, now its possible, for instance, to do: # perf trace -e rseq_slice_yield --max-stack=16 Here is an example with the 'sendmmsg' syscall: root@x1:~# perf trace -e sendmmsg --max-stack 16 --max-events=1 0.000 ( 0.062 ms): dbus-broker/1012 sendmmsg(fd: 150, mmsg: 0x7ffef57cca50, vlen: 1, flags: DONTWAIT|NOSIGNAL) = 1 syscall_exit_to_user_mode_prepare ([kernel.kallsyms]) syscall_exit_to_user_mode_prepare ([kernel.kallsyms]) syscall_exit_to_user_mode ([kernel.kallsyms]) do_syscall_64 ([kernel.kallsyms]) entry_SYSCALL_64 ([kernel.kallsyms]) [0x117ce7] (/usr/lib64/libc.so.6 (deleted)) root@x1:~# To do a system wide tracing of the new 'rseq_slice_yield' syscall with a backtrace of at most 16 entries.
